-- bezier curve drawing functions for playdate lua
-- these are based on de Casteljau's algorithm
-- this site has a nice interactive demo to compare both types of curve: https://pomax.github.io/bezierinfo/#flattening

-- draws a curve starting at x1,y1, ending at x3,y3, with x2,y2 being a control point that "pulls" the curve towards it
-- steps is the number of line segments to use, lower is better for performance, higher makes your curve look smoother
-- the playdate is kinda slow, so it's recommended to find a relatively low step number that looks passable enough!
function drawQuadraticBezier(x1, y1, x2, y2, x3, y3, steps)
  steps = steps or 8
  local d = 1 / steps
